Heyin a project of us we are using the legacy STMFlashLoader to flash firmware on a STM32F103 via the system bootloader on UART1, but wanted to migrate to STM32CubeProgrammer now. In this application the PC (Win10) which runs STMFlashLoader/STM32Cube...

I have a project which uses SPI DMA, and the SPI DMA appears to fail when I enable the instruction cache (ICache! not DCache), but otherwise appears to work perfectly fine. I do observe this for both a F722ZE and G491RE.I'm working on this since 3 we...

I know I'm not the first reporting such an issue here, but the "solutions" in the previous threads did not help.I yesterday have installed STM32CubeIDE 1.7.0 using the installer. When trying to run a code, a dialog opens saying "No ST-LINK detected!...

concenring optimization, I think I understand what it does, and I would have argued that the order of peripheral register calls is not changed, so what should it do ... but as you've suggested I did some tests with the optimization level ... and this...

many thx for your response, and the many hintsunfortunately, some I'm not able to answer or put through. Let me tell what I can say at this point in time:yes, I too considered critical timing issue, i.e., that the higher frequency/speed may spoil som...

noI found two simple workarounds by now, however:1) calling the stlink as external tool2) https://community.st.com/s/question/0D53W00000DGpMn/i-cant-use-the-stlink-in-stm32cubeide-even-after-updating-the-stlink-firmware, see response by Georgy Moshki...

many thx sir for your responseI have installed STM32CubeProgrammer now and while it does not work it gives a more useful info to why not: It says "Error: ST-Link V1 not supported"I didn't knew it would be V1, I always was under the impression it woul...

Posted on October 18, 2013 at 22:08Hey Mayla thx for your response :) in the above project I neither use PB5 nor I2C1 (I use I2C2) may I assume that the above code snippet would, in principle, be the way to go? cheers, Olli PS: I planed to use PB5 a...
